I have 2 computers connected through a netgear gigabit router and a my cable router is connected to my gigabit router also (so both my computers can access the internet). I can't network render when the cable router is turned on. I'm assuming it's because when the cable router is turned on, it changes my DNS suffix. I tried changing my DNS suffix on my computers to match the DNS suffix that I get from running the ipconfig (when my router is turned on) but it doesn't work. When I open up the network render utility, the computers can't connect with eachother, even though the DNS suffix is correct. But as soon as I turn off the router, I can network render. When my router is turned on, my DNS suffix changes to a comcast address because that's my internet provider. Is this an invalid address for network rendering? Is there anyway around this?

Thanks
